In the original paper, we used mixed-effects models with the effect statistic Zr (Fisher transformation of correlation coefficients) as the response, which can be written as (supposing that z denotes the n by 1 vector of effect sizes, Zr): where β is the a by 1 vector of fixed effects, X is an n by a design matrix associated with the effect sizes, u is the b by 1 vector of random effects (we had the four random factors in our analysis: Class, Family, Species and Study) and the ith element of u is normally distributed with the mean of zero and the variance of , Z is an n by b design matrix associated with the effect sizes, and e is the n by 1 vector of residual errors, normally distributed with the mean of zero and with the variance of divided by (n−3); note that 1/(n−3) represents the effect-size specific measurement error variance of Zr. We inadvertently estimated from the data in the original analysis. In meta-analysis, however, should be fixed to 1 ( = 1). Fortunately, our estimates of in all the original models were very close to 1 (such similarity is probably expected, because the variance of the z distribution is 1). Therefore, our original results are quantitatively very similar to those of correct meta-analytic models and our qualitative conclusions remain unchanged. We wish to refer readers to Nakagawa et al. (2011) for more detailed explanations of how correct meta-analysis can be implemented using existing computer programs. We apologize for the error.
